PyTorch

PyTorch is a newer, but growing deep learning library that is based on the Torch framework used for Facebook's deep learning algorithms. Unlike TensorFlow, PyTorch is not a wrapper that compiles to an underlying language, but is written to mimic native Python. If you have had any experience with Python programming, PyTorch will feel extremely familiar to you. 

PyTorch can be easily installed with:

conda install pytorch torchvision -c pytorch

Currently, PyTorch does not have a Windows distribution, which may make it out of reach for some users.
